> If a SolrCloud node receives a request with a local core name (not a 
> collection name), it will be handled by the local core.  But it even works 
> with a remote core -- it'll be forwarded to the node that has a core by that 
> name.  I think there's no use-case for that -- users should only reference 
> collections (any node) or a core on a node where it's known to exist (on that 
> node!) since it's a core not a cluster concept.  This got my attention 
> because the functionality requires iterating all collections.  This would 
> happen for any request when a collection/core is not known to the node (and 
> may not exist at all).  I shall remove this in Solr 10.
> There is exactly one test for this functionality -- 
> {{org.apache.solr.cloud.AbstractBasicDistributedZk2TestBase#addAndQueryDocs}}
